8.70 mm coolant-fed drill

The M.A. Ford Twister XD 7X+ is a new solid-carbide drill designed for high-performance holemaking in demanding materials. Internal coolant channels deliver fluid directly to the cutting zone for consistent chip evacuation and temperature control. It targets machine shops and production cells that require reliable deep-hole capability without peck cycles.

7X+ geometry and through-tool coolant

The 7X+ point geometry reduces thrust and improves centring on difficult alloys and hardened steels. Through-tool coolant delivery supports stable drilling at higher speeds while protecting the cutting edges from thermal shock. The shank is manufactured to standard tolerances for direct clamping in hydraulic or shrink-fit holders.

Replaces conventional external-coolant drills

Shops moving from flood-cooled or peck-drilling processes gain cycle-time reduction and longer tool life in deep holes. The step is justified when hole depth exceeds three diameters and material hardness makes chip control critical. Operations limited to shallow holes or soft materials will not see the same return.
